ELECTBOMAGNETI FISHING TOOL.

Application led November 7, 1321.

` To a whom it may concern.'

Be it known that I, CHESTER H. BEACH, a. citizen of the United States,residing at Racine, in the county of Racine and State of Wisconsin, haveinvented certain new and useful Improvements in Electromagnetic FishingTools, of which the following is a specification:

This invention relates to improvements in electromagnetic fishing tools,one object of the invention being to provide a. small portable tool ofthis character which may be used in and around automobile engines andmachinery in general for picking up nuts, bolts,

" and other small metal parts which may fall into obstructed places outof reach for removal by hand and diicult of removal in any other way.

Other objects of the invention will be apparent from the followingdescription, taken in connection withthe accompanying drawings, whereinone form of the invention is illustrated.

Figure 1 is a side elevation of a tool constructed in accordance withthe present invention; and

Fig. 2 is a vlongitudinal sectional view, taken through the electromanet.

Referring more in detai to the drawings- 10 designates an ordinaryelectric cable or cord, provided, intermediate its ends, with a suitableswitch 11. At one end the cord is provided with a connecting plug 12,

w which may either be of the single or double Contact type. At the otherend of the cord the two leads 13 and 14 are connected to anelectromagnetic coil 15, the central opening of which accommodates a baror rod 16, of soft iron or the like. The coil is suitably' insulated andthe rod 16 extends forwardly of the coil at its outer end, and isrounded at 16n at its tip. A ferrule 17, of brass or other non-magneticmaterial, is mounted on the cordlO and at one end 1s spun or crimpedinto the insulation of the cord, as at 17a. A suitable shell 18, alsopreferably of brass or some othernon-magnetic material, lits down overthe soft iron rod 16 and the coil 15 and Serial No. 513,324.

engages the ferrule 17 at its inner end, the said shell being pressed orsweated into firm engagement with the ferrule in order to anchor sameagainst displacement. In addition the rear edge of the shell may besoldered or otherwise 'secured to the Jferrule, if desired. The forwardend of the shell 18 is apertured, as at 18, to permit of the forward endof the soft iron core 16 projecting therethrough, the latter beingrounded, as above pointed out, at 16, this rounded portion conforming tothe contour of the forward end ot the shell. In order to preventaccidental displacement of the soft iron core relatively to the shelland, further, in order to impart rigidity and ruggedness to the entireassembly, it may be founddesirable that the forward end of the coretightly fit the bore or a crture 18a inthe end of the shell.

From tie above. description it will be'observed that an electromagneticfishing tool has been provided wherein the magnetic influence is exertedonly at the exposed tip 16 of the soft iron core, the enclosing shell18, of non-magnetic material, eliminating lateral attraction. Thisenables the operator in the use of the tool to lower the same throughobstructed assagesinto direct contact with the artic e to be raisedwithout such interference as would be occasioned in the event the toolwere subject to or exerted lateral attraction. Another important featureof the present improvements resides in the general arrangement andassembly of the parts, the same being of such a compact naturethat theelongated enclosing shell is of substantially the same diameter as thatot the electric cable or cord 10. Thus the tool maybe employed inlifting articles from narrow passages and other obstructed placespractically inaccessible in any other way.

It will be obvious to those skilled in the art that the presentimprovements are susceptible tc change and modification; and it is nottherefore desired to restrict the same, except as defined in theappended claim.

That I claim is:

In a tool of the class described, an electric cable, a errule tightlyfitted over said of said cable, and a core of magnetic material mountedin said coil with its tip rojecting into said aperture and lying ush 10with the outer end of said shell. l

In testimony whereof, I have subscribed my name.

CHESTER H. BEACH.
